the following text is adopted from the uscis website.

Those of you with conditional permanent residence either received your residence through a marriage relationship where the marriage was less than two years old at the time you became a Permanent Resident, or you received that status through an investment as an employment creation immigrant (EB-5).

所以你的朋友肯定是UNCONDITIONAL的.. 不用担心什么..
